Converter BLOW 91-200# TOSLINK (optical) to 2×RCA audio adapter

BLOW 91-200# TOSLINK (optical) to 2×RCA audio adapter converts a digital optical audio signal to stereo analog outputs. The adapter accepts a TOSLINK optical input and provides two RCA outputs (left and right), enabling connection of modern digital audio sources to older stereo systems, amplifiers or AV equipment that accept analog RCA inputs. The compact unit is intended for simple signal conversion in home audio setups, small studios and other environments where a digital-to-analog interface is required.

Advantages

The converter provides a straightforward and compact way to route digital optical audio to analog RCA inputs without requiring a full AV receiver. It supports standard stereo conversion for left and right channels and reduces the need to replace legacy audio equipment. Its plug-and-play design requires minimal setup and is compatible with a wide range of consumer devices that output S/PDIF via TOSLINK.

Suitable for

• Connecting TVs, set-top boxes or media players with TOSLINK outputs to stereo amplifiers
• Using digital audio sources with older speakers or receivers that only have RCA inputs
• Small home recording or monitoring setups where analog inputs are required

Key specifications

• Input type: optical TOSLINK (digital audio)
• Output type: 2×RCA (analog stereo: left and right)
• Signal conversion: digital (optical) to analog (RCA)
• Channels: stereo (2-channel L/R)
• Form factor: compact inline adapter housing

How to use

Connect the optical cable from your source device to the adapter's TOSLINK input, then connect RCA cables from the adapter's left and right outputs to your amplifier, receiver or speakers. Ensure the source is set to output audio via the optical port and that connected equipment is powered on. No software installation is required; the device performs real-time digital-to-analog conversion while powered by the connected source or an external power option if provided by the unit.

Usage recommendations

For best results use good-quality optical and RCA cables, set the source device to a compatible sample rate and disable any digital-only audio formats (such as multichannel Dolby/DTS) if the converter supports only 2-channel PCM. Place the adapter where it is protected from moisture and excessive heat, and confirm impedance compatibility with your amplifier to avoid level mismatches.
